Serious Wi-Fi Issue - Sprint HTC EVO 4G LTE

< Never Mind >

---

Instead of nevermind maybe telling us what happened and how you resolved would be super cool. I just got my evo lte and it keeps connecting and disconnecting from my wireless router and none of my other devices are having any issues.

---

My phone sees the SSID of my 5ghz N radio but won't connect. It does connect fine to other radio running n/g at 2.4ghz
Sent from my PG86100 using XDA

---

I am having the same problem with my wifi, it keeps connecting and disconnecting, but it only ses to happen when I browse the internet. Downloading apps and streaming content it stays connected.
Any ideas?

---

I was having a problem connecting to a non-broadcast SSID. The "fix" seemed to be going into wifi settings, select Wifi Frequency Band and put it into 2.4 off of auto. It connected great when I did that and didn't go in and out. I switched back to auto and haven't had a problem since. Might be helpful to some to try.

Wifi is weak for me. Where my laptop can get 1-2 bars, my phone is saying out of range.

ok everyone -
click on settings --> wi-fi --> menu (its soft button upper right hand corner) --> advanced
then click on "Keep Wi-Fi on during sleep" and it'll stop trying to auto disconnect / connect spastically trying to save a little battery juice.

If you have weak wi-fi, then on this advanced screen, check th circle next to "Best Wi-Fi performance" and it'll kick it into high gear.
I am shocked at the wifi in this, i can see networks several blocks over i can't even see on my desktop or any other device for that matter. it's just one or no bars, but it sees everything around here.

Edit: I think I have fixed the problem (at least for now). I forgot the network and added it again and it's working perfectly.
(I rooted my phone last night)
I tried all of the things that you said, and am still having wifi issues. At my home, wifi connected without problem, but was extremely slow. So slow that it wasn't even usable (much slower than 3G!!!). All other devices I tried have no problems (E4GT, iPad, laptop).
I tried rebooting several times, with no results.
Now I am at school on a different network and it won't even connect (iPad still connects perfectly). Below the wifi network name in settings it goes between "saved" and "connecting".
Is anyone else having these same issues?

I would not recommend using "best wifi performance." On previous htc devices if you used this option it caused a wake lock on the device and didnt improve wifi at all.

This describes my problem exactly. I have tried toggling all of the WiFi options in every permutation, and I can't seem to maintain a stable WiFi connection.

I'm on my way home right now. I got it working at school, but I'll try now at home and see if it's working. Did you try completely forgetting the network?

I was having wifi issues as well when I first got my Evo LTE, all of my other wifi devices in the house were functioning fine and it was really starting to piss me off saying it was out of range and it was right next to it.
So just for the heck of it I rebooted my router and it fixed everything. So even if all your other devices are good, it cant hurt to give the router a power cycle.

Yep, did the same thing. Unplugged the router (Motorola Router) and plugged it back in. Everything works perfectly now.

I have a 300n linksys with the tomato firmware on it.

kinda unrelated question - (should i put this in it's own separate topic post??)
How do you set wifi priority, so it'll stay on the one i want it to connect to, not the strongest, or first one it saw, etc etc. can i order the 'saved' networks in any kind of priority list?

---

Has anybody found a fix for this? I have tried rebooting the router and my phone. I tried different routers. I tried a factory reset on the phone. Nothing is fixing it. Is anybody else still having this problem?
For those who have fixed it, what did you do? If WiFi works on your network, have you tried additional networks?

Ever since rebooting my router, I haven't had a problem.
Have you tried a different network (or did you just change routers on the same network)?

Apparently this is the thread for this issue... Didn't see this when I started the new one.
my original text below.
-------------------------------------------
Under settings/wifi/advanced, I have "keep wifi on during sleep" set to always. Yet after being off for a while, wifi seems to turn off. That is, upon waking phone from sleep, I can see it reconnecting to wifi, THEN my email is downloaded (k9 set to imap push). This indicates the above setting is not being respected.
Under "settings/more/usage/mobile network" is also set to on. This would suggest that even when wifi is not available, 3g/4g would still be used. This also does not seem to be the case. When waking the phone from sleep, I can see it reconnecting to 3g, then immediately connecting to wifi.
The goal is to have data enabled, even when the phone is sleeping so email can be received. The old evo 4g had a setting to keep data on even when phone was asleep.
Suggestions?

My solution
------------------------------
Ok.... After 2 hrs I made some headway.
Read this thread - http://forum.xda-developers.com/showthread.php?t=1590884 . Apparently the one x suffers from this issue to (though not all of [email protected]#).
There's a hidden menu available showing these options.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Initially, the top most, "put data connection to sleep" was checked. I unchecked it, then waited 20+ minutes. Upon waking, wifi was still connected.
Access to this HIDDEN menu is through your launcher's/activities shortcut. If you're using the stock sense launcher, you won't have this, so follow the instructions in this thread - http://forum.xda-developers.com/showthread.php?t=1627517 .
Although this fix didn't work on the one x, it appears to be working on the evo during my time testing. The real test will be tonight. If I have wifi in the AM, then this works 100%. If not, back to the drawing board
----------------------------------

this isn't the fix unless its just after low power threshold, the fix is in one X forums, you need root and modify some htc system files through shell

---

^^Confirmed. Wifi still seems to drop although the wifi icon remains present in the status bar. Looking at the wifi devices connected to the router clearly shows no evo connected .
I am rooted, so will have to explore the other fixes in the one x forum or wait for an ota update.
